How Image Resizer Works
This tool runs entirely client-side: your image is never uploaded to a server. Once loaded, the image's natural width and height are read directly in the browser and used to populate the starting dimension fields.
You can resize by entering an exact target width and height, or by percentage scale relative to the original size; when "lock aspect ratio" is checked, changing one dimension automatically recalculates the other to keep the image proportions consistent and avoid stretching or squashing.
On resize, the image is redrawn onto a canvas at the new dimensions using the browser's canvas scaling, then exported at your chosen quality — a straightforward resample rather than any AI upscaling, so shrinking an image looks sharp while significantly enlarging one may look softer.
